PAPER-REGISTERING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 528,657, dated November 6, 189 4. Application filed June 5, 1893- Serial No. 476,580. (No model.)

To all whom it may concern..-

Be it known that I, TALBOT O. DEXTER, of Fulton, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Paper Registering Machlnes, of which the following, taken in connect1on with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of devices which are employed for automatically reglsteringor adjusting to proper alignment sheets of paper in process of being fed to a paper-folding machine or other machine designed to operate on a single sheet at a time.

It has hitherto been found very difficult to provide a registering device of sufficient sensitiveness in its action to operate with the necessary accuraoyon sheets of paper of different grades or qualities, and fed irregularly or which may be carried out of proper alignment in their transit in the machine.

The object of this invention is to overcome the aforesaid difficulty by automatic and reliably operating means, and to that end the lnvention consists in the novel construction and combination of parts hereinafter described and specificallyset forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a paper folding machine equipped with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged side view of the registering mechanism. Fig. 4 is a top plan view of the same. Fig. 5 isa vertical longitudinal section on line at, w, in Fig. 4:. Fig. 6 s a View of the opposite side of said registermg mechanism. Fig. 7 is a plan view of the carriage of said mechanism with the lower parts of the mechanism connected thereto. Fig. 8 is a perspective view of the arm which carries the presser roller of the registering devices. Fig. 9 is a perspective view of the cam which actuates said arm, and Fig. 10 is an outer end view of the arm in connection with said cam.

Similar letters of reference indicate corresponding parts.

ff and -ffare the tapes or conveyers which carry the paper across the top of the folding rollers LL- and to the stop or end-gage -g-- which arrests the move:

ment of the paper so as to cause it to lie with the center of its length under the folding blade O. The paper usually requires registering and adjusting in its position after it has been carried to the end-gage g in Upon the said guides is mounted a longitudinally movable carriage F- which is adjustably confined in its position by means of the horizontal screw E- which is parallel with the guides -'BB and journaled in the pedestal B, and is provided at its outer end with a hand-wheel E', and has its inner end passing through the nut N affixed to or integral with the carriage F. In bearings on the under side of said carriage is journaled a shaft b+ disposed at right angles to the guides or parallel with the conveyers f'f', and to this shaft is fastened the roller -R- which has the top of its periphery protruding through an opening in the top of the carriage so as to be in prox- 8o.

imity to the passage of the paper, and is re- ,volved toward the side of the machine or laterally from the line of travel of the paper. The roller R receives its rotary motion from the actuating mechanism of the paper conveyers ff by means of a spiral gear -b' fastened to the shaft -b and meshing with a spirally toothed pinion b" at tached to a shaft a, which is at right angles to the paper conveyors or parallel with. go

the carriage -F and journaled at its inner end in a hanger a fastened to one of the guides B, and at its outer end in the pedestal -B-, and has attached to ita gear F'- which meshes with one of the gears of 5 the usual train employed on the folding machine. Over the roller --R and parallel therewith is another roller -R pivoted to a suitable vertically movable support which allows it to be raised sufficiently for the paper I00 in transit to pass freely between the two rollers, and subsequently fall upon the said paper and press the same upon the lower roller -R which by its frictional contact therewith draws the paper into proper alignment with the folding rollers and blade. For this purpose I provide the lower roller -R with a facing of rubber or other suitable material adapted to obtain the necessary frictional hold on the paper. The upper roller is revolved simply by its frictional bearing on the paper moved by the lower roller. The aforesaid Vertically movable support I preferably form of an arm -O- pivoted at one end to a rock-shaft -c journaled in a bracket F"- secured to the top of the carriage F. The presser-roller --R'- is pivoted to the free end of the arm O. The rock-shaft -creceives its motion by a miter pinion c"- fixed thereto and meshing with a similar pinion -cZ'- attached to a rock-shaft -d which is disposed at right anglesto the line of paper conveyors -f-f and has an arm G- attached to its outer end. This arm is connected by a rod e' to the upper end of another rockarm -I which is pivoted intermediate its length to the frame --A and has pivoted to its lower end a roller by which it bears on a rotary cam I-I. The arm I- is held in its bearing on said cam by a rod e connected to the arm above its pivot or fulcrum and passing freely through a rigid stud e attached to the frame A- and having affixed to it a collar ibetween which and the stude is a spiral spring 41 surrounding the rod and bearing on said collar and stud and thereby forcing the rod toward the rock-arm -I, as shown in Fig. 1 of the drawings.

The heel or pivoted end of the roller-carrying arm --C has projecting from its side a cam-shoulder C- upon which bears a cam o fastened to the rock-shaft c, the motion of which latter thus alternately lifts and drops the arm-C and causes the roller R to rise and allow the paper to pass between it and the lower roller R and subsequently drop upon the paper and press the same onto the lower revolving roller which shifts the paper laterally to the side-gage as aforesaid. To arrest the said lateral movement of the paper immediately after it has been registered by the side-gage I employ an electrically operated stop-motion, which obviously is susceptible of many variations in the details of its construction. Hence I do not wish to be limited specifically to the construction hereinafter described.

The construction shown in the annexed drawings for an exemplification of such stopmotion is as follows: On the bracket -F- are mounted electro-magnets DD connected to an electric circuit in which -S- denotes the battery. The armature -D'- is affixed to a lever -D" which is fulcrumed or loosely mounted on the rock-shaft cand is thus pivoted axially in line with the pivot of the roller-carrying arm O. The inner end of the lever --D is extended under the arm -O- so as to engage the same from beneath and lift the same as hereinafter described. I preferably provide said arm with an adjustable set-screw by which it bears on the lever D as shown in Figs. 3 and 5 of the drawings. To cause the lever D to alternately lift and drop the arm C I employ a circuit-making and breaking lever consisting of a movable side-gage --7c in the path of the paper shifted by the rollers -RR'-. This lever is pivoted to a hanger 7c' on the carriage --F- and is held normally in its circuit-breaking position by a weighted arm Z-- connected thereto in a suitable manner, as shown in Fig. 5 of the drawings, in which it is connected to another arm -7c" extending laterally from the pivoted end of the lever. On this arm is mounted an insulated block Z'-- provided with a binding-post Z-- and having extending from it the metallic spring-finger -mwhich constitutes one of the electric terminals. A hanger-n is attached to the carriage F- and insulated therefrom, and to the foot of this hanger is connected an adjustable vertical set-screw -n which serves as the other electric terminal. Said set-screw is under the free end of the finger --mso as to come in contact therewith when the lever 7c is tilted outward as shown in Fig. 3 of the drawings. The hanger -n is electrically connected with one of the magnets -D-- by wire e. The other magnet is connected directly with the battery --S- by wire -e. The finger m is electrically connected with the battery by wire -0- attached at one end to the binding-post -Z-- and at the opposite end to a metallic bracket pfastened to and insulated from the carriage, F, and having extending from it a metallic tinger o' from which extends a wire -0"' to the battery -S.

The operation of the described registering mechanism and its electric stop-motion is as follows: As the paper is passed to the endgage g by the conveyors -ff' said paper becomes aligned by its encounter with said gage. The arm --C- with the roller -R is then lifted by the cam c of the rock-shaft c pressing down the shoulder --G' of the aforesaid arm. The lifting of said roller allows the paper to pass between it and the lower roller -R. The motion of the rock-shaft cis so timed with the motion of the conveyers -f--, that the cam -c relieves the shoulder C'- from the downward pressure and allows the arm -O- to drop and cause the roller R- to press the paper upon the lower roller -R- which is in constant motion, and, by its frictional hold on the paper, draws the same laterally into alignment with the folding roller. In this movement the edge of the paper comes in contact with the free end of the circuit making and breaking lever, and pushes said lever into its circuit-making position, as represented in Fig. 3 of the drawings. The magnet becoming thus energized causes the armature to be attracted, and in this motion the armaturelever D"- lifts the arm G- sufiiciently to relieve the paper from the pressure of the roller R'. The lower roller R thereby loses its frictional hold on the paper and consequently the motion of the.

paper is arrested.

. nearly balanced by the weighted arm -Z it requires only a very slight pressure of the paper upon said lever to tilt it into its circuit making position. Hence the described electric stop-motion is very sensitive and reliable in its action.
